Final answer:
A nurse should administer an antiviral medication like valacyclovir for a client displaying genital lesions indicative of genital herpes. This medication helps to prevent or shorten outbreaks and reduce the chance of transmission. For a yeast infection, an antifungal medication would be appropriate.
Step-by-step explanation:
Which Prescribed Medication for Genital Lesions:
A nurse can expect to administer an antiviral medication such as valacyclovir to a female client exhibiting genital lesions, consistent with genital herpes, as indicated in the provided illustration. It is important to note that while no cure exists for herpes infections, antiviral medications like valacyclovir help in preventing or shortening outbreaks and reducing the risk of transmission. In the scenario presented, especially given the description of vesicles commonly developing on the vulva, such a prescription would align with established treatment protocols for genital herpes.
In cases where a secondary yeast infection by Candida albicans is suspected, especially after the use of antibiotics, an appropriate oral medication would be an antifungal such as fluconazole. However, based on the description of genital lesions, antifungal treatment may not be suitable unless there is clear evidence of a concurrent yeast infection.
